Multiplication of Binomials Using Line Method

The Line Method visualizes multiplication of binomial expressions. You just simply count the intersections. you divide the area where you draw the lines that represent the terms of the binomial expression. Divide the area into three parts , the intersection on the left most part is the product of the two variables it represents the quadratic term, the middle part is the sum of the upper and lower intersection and its sum is the linear term and the right most portion of the area is the product of the constant terms.
